I have a Chevy 3500 (well 2 of them) both crew cab dually, both 4x4, both allison trany, one is an 8.1 gas and the other a 6.6 turbo diesel AND a Yukon XL 5.3
As far as towing, the Yukon can not touch the trucks. When I had my 7x14 enclosed track trailer, it would tow, but the wind would kill it the diesel never knew it was there. even my 7x17 open utility trailer will make the Yukon dance at higher speeds with some weight on the trailer. I can run a 38 ft toyhauler 5th wheel at 75-80 with no prob with the trucks.
We are a fam of 5 and can go comfortably on a 10 hr trip in the crew cab (ages 15,12 and 9) with the same amount of fighting we get in the Yukon even though the kids are spaced farther apart.
